Answer: 1 is otiose, 2 is unimpeachable, 3 is puerile , 4 is recalcitrant

When the verdict was read, the defendant, a former executive, shocked courtroom observers with puerile remarks. Bailiffs then dragged the recalcitrant prisoner from the courtroom, while he kicked and clawed at any court official within reach.
